DETAILED DESCRIPTION

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 7As shown, a reducer end cover mold frame includes a mold frame body 1, a mold 2, a plurality of positioning columns 3 and a driving mechanism 6. The bottom end of the mold 2 has a plurality of positioning grooves 4. The positioning columns 3 are rotatably installed on the top of the mold frame body 1. The driving mechanism 6 is installed on the mold frame body 1 and is connected and cooperated with the positioning columns 3.

[0027] When installing the mold 2, first we match the positioning groove 4 at the bottom end of the mold 2 with the positioning column 3 on the mold frame body 1, so that the mold 2 can be pre-positioned with the mold frame body 1, and then start the driving mechanism 6. Under the drive of the driving mechanism 6, multiple positioning columns 3 can be rotated to a set angle, so that the positioning column 3 and the positioning groove 4 can be snap-fitted through the snap assembly 5, and then the mold 2 is locked, that is, the mold 2 is limited and fixed to complete the installation.

[0028] It can be seen that the automatic installation and disassembly of the mold 2 can be achieved by rotating the positioning column 3 through the driving mechanism 6, and the cooperation between the positioning column 3 and the positioning groove 4 can also enable the mold 2 and the mold frame body 1 to be quickly pre-positioned, thereby greatly improving the disassembly efficiency of the mold 2.

[0029] The present application does not limit the specific structure of the driving mechanism 6, and only provides a specific structure for reference below:

[0030] like Figure 6 As shown, the driving mechanism 6 includes a driving device 601 and a transmission assembly 602 installed in the mold frame body 1, the input end of the transmission assembly 602 is connected to the output end of the driving device 601, and the output end of the transmission assembly 602 is connected to the positioning column 3. It can be understood that the driving device 601 can drive the positioning column 3 to rotate through the transmission assembly 602, thereby realizing the installation and removal of the mold 2.

[0031] As a further description of the above technical solution: Figure 6 As shown, the transmission assembly 602 includes a driving wheel 6021, a plurality of driven wheels 6022 and a plurality of connecting rods 6023. The driving wheel 6021 is rotatably installed in the middle of the mold frame body 1 and is connected to the output end of the driving device 601. The positioning column 3 extends into the mold frame body 1 and is connected to the driven wheel 6022. The two ends of the connecting rod 6023 are respectively hinged to the driving wheel 6021 and the driven wheel 6022.

[0032] Specifically, the driving device 601 here can preferably be a hydraulic cylinder or a pneumatic cylinder, the hydraulic cylinder is hingedly installed in the mold frame body 1, and one end of the piston rod of the hydraulic cylinder is hingedly connected to the extension part of the side of the driving wheel 6021. The extension or shortening of the hydraulic cylinder can make the driving wheel 6021 rotate, and the driving wheel 6021 acts on the connecting rod 6023 to rotate, and the connecting rod 6023 can drive the driven wheel 6022 to rotate, thereby making the positioning column 3 rotate synchronously.

[0033] It should be noted that the drive device 601 here can actually be driven by a motor, and the transmission component 602 can actually be driven by a belt drive or a chain drive. However, since multiple positioning columns 3 share one drive device 601, if a motor is used at this time, the power output may be insufficient. If a hydraulic cylinder is used, a large torque force can be quickly transmitted, which is suitable for engineering occasions that require high power output. At the same time, it has high reliability, long service life, and low maintenance cost. If the transmission component 602 adopts a belt drive or a chain drive, the structure will be complicated, and the synchronous belt or chain will easily loosen after long-term use, which will have a certain impact on the transmission accuracy. However, the transmission component 6023 and other components are used for transmission, which has a simple structure and good rotation accuracy. It can obtain a precise rotation angle and can provide good stability and accuracy.

[0034] Of course, it is also preferred to use four groups of positioning columns 3, that is, four positioning columns 3 are distributed in a rectangular shape at the top of the mold frame body 1, that is, they are located at the four corners or four sides of the top of the mold frame body 1, thereby performing four-point positioning on the mold 2, thereby improving the limiting locking effect of the mold 2.

[0035] In one embodiment of the present application, the buckle assembly 5 has multiple structural forms, including but not limited to the following two:

[0036] Structure 1: Figure 3 As shown, the buckle assembly 5 includes a clamping block 501 and a clamping slot 502 . The clamping slot 502 is arranged on the outside of the positioning column 3 , and the clamping block 501 is arranged on the inner wall of the positioning slot 4 . The clamping slot 502 includes a vertical portion and a horizontal portion perpendicular thereto.

[0037] It can be understood that when installing, the block 501 will move downward along the vertical part. When the block 501 moves downward along the vertical part to the extreme position, the mold 2 and the mold frame body 1 complete the pre-positioning installation, and the snap assembly 5 is in a disengaged state. Then the positioning column 3 will rotate under the drive of the driving mechanism 6, and the block 501 will rotate from the vertical part to the horizontal part, thereby limiting and locking the mold 2.

[0038] Structure 2: Figure 4As shown, the buckle assembly 5 includes a clamping block 501 and a clamping slot 502 . The clamping block 501 is installed at the top of the positioning column 3 , and the clamping slot 502 is arranged at the top of the positioning slot 4 .

[0039] It is understandable that during installation, the card block 501 and the card slot 502 are in a positive corresponding state (such as Figure 5 As shown in Figure a), when the block 501 is correspondingly inserted into the slot 502, the mold 2 and the mold frame body 1 complete the pre-positioning installation, and the buckle assembly 5 is in a disengaged state; then the positioning column 3 is driven by the driving mechanism 6 to rotate, so that the block 501 is rotated and dislocated inside the slot 502 (as shown in Figure a). Figure 5 As shown in Figure b), the buckle assembly 5 is in a limited position state, thereby limiting and locking the mold 2.

[0040] It should be noted that both structures can meet actual needs, and technicians in this field can make a choice based on actual conditions.

[0041] When adopting the above technical solution, the following problem may occur: since all the positioning columns 3 are actually locked by a driving device 601 (that is, the driving device 601 must maintain an extended or shortened state), if the driving device 601 fails, the driving wheel 6021, the driven wheel 6022 and the connecting rod 6023 may be in a free state, which will affect the stability of the installed mold 2.

[0042] In order to solve the above-mentioned problem, one of the embodiments of the present application is as follows: Figure 7 As shown, the driving wheel 6021 is rotatably mounted on the mold frame body 1 via the rotating shaft 7, and the rotating shaft 7 and the mold frame body 1 are matched via a clutch structure 8.

[0043] It can be understood that when the mold 2 is installed and locked, the clutch structure 8 is in a limited state, thereby maintaining a limited state for the rotating shaft 7; of course, when the mold 2 is disassembled, the clutch structure 8 will also be in a separated state under the forced driving of the driving device 601, that is, the clutch force of the clutch structure 8 will not be very large, and will not interfere with the operation of the driving device 601.

[0044] As a further description of the above technical solution (such as Figure 7 As shown): The clutch structure 8 includes a clutch slot 802 and a clutch block 801, and there are multiple ways to install the two, including but not limited to the following two:

[0045] Method 1: The clutch groove 802 is arranged outside the rotating shaft 7, and the clutch block 801 is elastically slidably installed in the mold frame body 1 through a spring.

[0046] Method 2: The clutch groove 802 is provided in the mold frame body 1, and the clutch block 801 is elastically slidably installed on the outside of the rotating shaft 7 through a spring.

[0047] It is understandable that when the mold 2 is installed and locked, the clutch block 801 is matched with the clutch groove 802 under the action of elastic force, thereby limiting the rotation shaft 7. At this time, the clutch structure 8 is in a limited state, so that when the driving device 601 fails, the positioning column 3 and the positioning groove 4 can be stably snap-fitted. When the mold 2 is disassembled, the rotation shaft 7 will rotate in the driving device 601, thereby forcibly separating the clutch block 801 and the clutch groove 802, so that the clutch structure 8 is in a separated state.

[0048] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
